The selling point here is data—smartphone customers are using more of it, and giving subscribers a roomier cap makes T-Mobile’s entry-level offering more attractive than before. And T-Mobile is hyping the fact that its plan doesn’t charge a fee if you go over that 2GB cap. “The old guard telecoms punish people for using more data on their networks with crazy overage charges and fees,” John Legere, T-Mobile’s president and CEO, said in a statement announcing the revised plan. (Under Simple Starter, T-Mobile simply turns off data once you’ve hit your ceiling; the company offers on-demand data passes if you end up needing more data.)

The revised Simple Starter plan launches on next Wednesday, September 3. T-Mobile called the $5 extra a month for additional data a “limited-time” offer. It's also optional—you can keep paying $40 for 500MB if you don't want to spend more.
